Explanation:

Past perfect tense is primarily employed to display 'the actions that occurred in the past before a further action took place.' It assists in clarifying the time of action by telling which occurred before. It is formed by using 'had + Past participle form of the verb' that denotes the previous action(in the past) while the latter is written in past indefinite. Thus, the given sentences are completed by using this rule.
